To all whom it may concern.' l

Be it known that we, JOHN Scnlns and Mor'r WYANT, citizens of the United States, residing at Anderson, in the county of Madison and State of Indiana, have -jointly invented certain new and useful Improvements in Glass-Tank Furnaces, of which the following is a speciiication.

Our invention relatesto glass tank furnaces and has for its object the providing of a furnace of this character capable of producing different kinds of glass, for instance, amber glass and flint glass, simultaneously un-l der one fire further in so arranging the melting chambers and working chamber as to permit the employment of a large number of working openings; which lattei` also has the advantage, when a plurality of kinds of glass is being produced, to serve each kind from a` large number of openings for enablinglarge production to be had.

Our invention consists in providing a plurality of melting chambers and a working chamber arranged to the front of the collective melting chambers, in providing a heat delector for said working chamber adjacent said meltin chambers, in providing said working chamber with a plurality of glassmetal compartments, in providing regenerative heating chambers having openings -into said melting chambers at one side of said 'collectiva melting chambers and arranging said melting chambers and working chamber for `causing the heat to cross said melting chambers and said working chamber in sub/stantially a curved sweep, and the Invention will be further readily understood from the fol-1 lowing description and claims, and from the drawings, in which latter:

Figure 1 represents a horizontal section of our im roved device on aline correspondinor to the ine v-fv of Fig. 2. Fig. 2 is a vertica section of the same on aline corresponding to the line :zz-gfx of Fig. 1. fFig. 3 is a vertical section of the same on aline corresponding to the line y-y of Fig. 1. For comparison and clearness this section line is also indicated at Z-Z of Fig. 2.

A A represent melting chambers in which the raw material is melted, the raw material` being fed through charging holes a a which may if desired be closed in any suitable manner between charginfs. These melting -chambers are preferably arranged end to end with the wall B between them. They may also be separated by the space b.

'shaped 1n cross-section.

. C is the working chamber which is a'r-4 I ranged in front of the melting chambers, from which its lower or glass-metal portion is separated by the walls D D', in which there 60 are throats d d for the glass-metal below the level of the lass-metal, the glass-metal in practice iisuiilly attaining a height in these. glass chambers or tanks indicated by the dotted line Z in Figs. 2 and.A

E is the outer or serving wall-of the working chamber, which is provided with working openings e, through w lich the glass-metal is taken from the melting chamber for subsequent operations. The glass blowers or 70 other glass manipulating o )erators are usu ally positioned at the wall n or front of the furnace. A deflcctor-wall G is located adjacent the melting chambers and is preferably of curved form in its horizontal cross-section 75 with the curved^portion extending into the working chamber. It is shown as extendin forwardl of the wall B.. The outer wall l preferab y extends in a. curving sweep in front of the working 'chamber t0 substan- 80 tially the outer ends of the melting chambers.

LV is the dome of thc furnace. W'e prefer to provide the dome with an outer slope W', sloping toward the outer walls, and with an vinner slope' W2, thel latter serving as a con- 85 tinuation of the heat deilecting wall for properly deilecting and coniimng the currents 1n proper coulse, the' constructlon forlnlng a curved passage for the heat whichl is dome- If desired the lower or glass-metal containing part of the working chamber may be. divided for formino aplurality of glass-metal compartments, wrhich we have shown accom- 'plished by the dividing wall H for forming the 95.

glass-metal compartments I I. The con struction and arrangement of our improved glass tank furnace permits a large number of worzringo )enings to be employed. The dividing wal 'H may be so placed as to divide 10o the melting chamber into glass-metal compartments having an equal number of working openings, or the dividing wall may be so placed as to make one or the other cornartment proportionately larger for provid- 105 ing each with a different number of working openings. The working chamber is shown at the front of the collective melting chambers, the fuel being supplied to rear of said melting chambers, the ufuel openings also 11o serving alternately as exhaust passages for the heat in the form shownf il K- K are regenerative chambers for the the air, which chambers may contain suitable brick checker-work of ordinary construction'for alternately receiving heat from the exhaust and imparting heat to the incoming fuel.

Mill represent the gas passages and N N represent the air passages, vhrch passages merge into the fuel ports O O for conducting the mixed gas and air into the respective melting chambers, there being preferably a plurality of these gas and air passages and u el ports for cach melting chamber.

The fuel or gas and air may be supplied from any suitable source t the regenerators and the exhau'st received therefrom in any suitable manner, suits le passages and valves being provided for determining the course of the currents of fuel and heat, or regulating the same, and We have exemplifie an arrangement and means for accomplishing this, although these may be changed Without departing from the spirit of our invention- P shows a gas suprly passage whichxmay have a regulating valve p therein.

Q shows an air supply passage which may have a regulating valve q therein.

R is an exhaust passage, which may be the tunnel to a suitable stack for creating the proper draft for causing the currents of comustion to properly travel.

S S represent gas passages to the ,gasrei generators, leading from the gas supply passa e P.

I' T represent air passages-to the air regenerators, leading from the air supply passa e is an opening between the Oas passages 40 rs S S- and the exhaust assage and U an opening between t e air passages -T T and said exhaust passage.

.V is a gas reversing valve for directing the gas selectively through the .gas passages to the respective gas regenerators.

, V' is an air reversing valve for directing the air selectively through the air passages to the respective air regenerators. Valves of any desirable construction may be employed. Suitable means are also provided for reversing the exhaust from these regenerators, that is to say, when the air and gas supply for one set of regenerators is opened the exhaust for the other set of regenerators is also opened for enabling the current of combustron to cross the melting chambers and the working chamber of the glass tank furnace. r We have shown the reversal of exhaust aceorgalished by the valves V V'.

X r represent s aces or passages between the respective me ting chambers and the working chamber.

In operation, assuming that the mixed air and gas are passing through the passages M N, the fuel and heat will pass through the ports O across the melting chamber A, the

space X, the .Working chamber C, the spaceh', theme-itin7 chamber A', thence through the ports O', t e

when the currents are reversed they may in turn heat the incoming fuel, and thence through the p assages S T and the exhaust' t e fuel and heat following the passage R, course of lthe arrows s, the current, in the referred form, crossing the. melting chamoers in substantialllI opposite directrons and passing through t substantially curved currents. When the fuel and heat have been passed' a given time in the direction of thearrows, the reversing valves are reversed for causing the currents to ass in the reverse direetron.
